The 19-year-old had been in hospital since 27 December after consuming rat poison.

The 19-year-old had attempted suicide on 27 December by consuming rat poison and was at the Government Rajaji Hospital in Madurai.

“He was fine, but as he saw news that his blood was transfused to a pregnant lady, he thought he should not live and consumed rat poison,” the donor’s mother told ANI.

Immediately after the issue was brought to the notice of the authorities, three health workers of the blood bank at the government hospital in Sivakasi were suspended for labelling the HIV positive blood as safe.

On further inquiry, it was found the hospital authorities had detected that the donor had HIV as early as 2016, when he donated blood at a camp in Sattur.

But as the teenager was out of town when a counsellor phoned him with the news, he was asked to report to the hospital as early as possible.

On December 27, the donor had attempted suicide by consuming rat poison as his family struggled to deal with the issue.
